Description

Water-distribution nozzle for cooling tower

Technical field

The utility model relates to a kind of tubular type water-distribution nozzle that is used for counterflow cooling tower.

Background technology

The tubular type water-distribution nozzle of counterflow cooling tower use at present generally comprises a main body pipe and is arranged on a flat splash box of main body pipe below.We know that water-distribution nozzle is the important core part in the cooling Tata core components, and the height of the thermal performance efficient of cooling tower has significant relationship with the performance of water-distribution nozzle water spray; Cloth water quality quality directly influences the thermal performance of cooling tower.

But existing water-distribution nozzle, the splash box plane is an entity, can produce obvious umbrella during water distribution, and the hollow area is bigger, and the globule is not of uniform size, and water distribution is inhomogeneous, influences cooling tower thermal performance (good cooling results).

The utility model content

It is tiny evenly not have umbrella, no hollow, water spray when the purpose of this utility model provides a kind of water distribution, to improve the water-distribution nozzle of cooling tower thermal performance (cooling effect).

This water-distribution nozzle for cooling tower comprises a main body pipe, and it also comprises plural disc; Each disc has a main body panel and is distributed on the blade of main body panel periphery, and the central part of main body panel has pod apertures; Each disc is positioned at main body pipe below, and coaxial with the main body pipe; Adjacent two discs up and down satisfy: the pod apertures internal diameter of the disc of the pod apertures internal diameter of the disc of the main body panel external diameter of the disc of the main body panel external diameter of the disc of the blade external diameter of the disc of the blade external diameter of top disc＞following＞top＞following＞top＞following.

This water-distribution nozzle also can be described as the tubular type multilayer vane type disc shower nozzle that dabbles, its beneficial effect: water flows down in the main body pipe, be flushed to uppermost disc earlier, part current flow downward through the pod apertures of the top disc, and a part of current flow downward through the blade of uppermost disc and the hydrophobic gap between the blade.The utility model is because adjacent two discs up and down satisfy the size relationship of characteristics, make adjacent two discs up and down have complementarity in radial direction, make water distribution not have umbrella, no hollow, water spray is tiny evenly, has guaranteed cooling tower thermal performance (cooling effect).

Above-mentioned shower nozzle is seen from top to bottom, and each blade becomes dextrorotation to be arranged on the main body panel.The blade that dextrorotation is arranged makes that flowing water flow has the dextrorotation phenomenon from the top down, can effectively prevent the generation of umbrella.

The taper high in the middle of above-mentioned shower nozzle, disc are, that periphery is low is so that the current on the disc can flow to the periphery of disc smoothly.

Above-mentioned shower nozzle, the outer contour of blade is a smooth transition curve, so that water distribution is more continuously, evenly, no hollow phenomenon.

Above-mentioned shower nozzle, the taper that pod apertures is big up and small down.Preferably, the upper end of pod apertures is up big and down small horn mouth.The taper that the endoporus of main body pipe is big up and small down.

Above-mentioned shower nozzle is provided with a sleeve pipe that becomes to removably connect with the main body pipe in the endoporus of main body pipe.Like this, can change the sleeve pipe of different interior hole sizes according to different discharge.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to the tubular type multilayer vane type disc shown in Figure 1 shower nozzle 10 that dabbles, have a main body pipe 4, sleeve pipe 5 and 1,2,3 and two dowels 6 of top-down three discs.A sleeve pipe 5 that becomes to removably connect with the main body pipe is set in the endoporus of main body pipe 4.Sleeve pipe 5 can be changed, referring to Fig. 8,10.For the sleeve pipe among Fig. 8, the taper that the endoporus of sleeve pipe is big up and small down, its upper end has the flange 51 of outside turnover, and flange 51 is connected to the recess place of main body pipe 4 upper ends.Difference for the sleeve pipe of the sleeve pipe among Figure 10 and Fig. 8 is: the endoporus aperture of the sleeve pipe among Figure 10 is less; The outer wall of the sleeve pipe in Figure 10 has four reinforcements 52.

Each disc has a main body panel 7 and is distributed on 6 blades 8 of main body panel periphery, and the outer contour of blade is a smooth transition curve.On look down, 6 blades become dextrorotation to be arranged on the main body panel.Be provided with hydrophobic gap between blade and the blade, guarantee that water distribution is tiny evenly.The central part of main body panel all has pod apertures 9.The taper that pod apertures 9 is big up and small down; The upper end of pod apertures is up big and down small horn mouth.The taper high in the middle of disc is, that periphery is low.Each disc is positioned at main body pipe below, and coaxial with the main body pipe.Blade external diameter referring to Fig. 2-7, three disc 1,2,3 is respectively D, D1, D2, and main body panel 7 external diameters of three discs 1,2,3 are respectively Pod apertures 9 maximum inner diameters of three discs 1,2,3 are respectively

Article two, dowel 6 links into an integrated entity main body pipe 4, top-down three discs 1,2,3, and is injection molded with high-quality engineering plastics, and the working condition that can satisfy high temperature, cold fully uses down.Article two, the cross section of dowel 6 becomes flat ellipse taper, and with pod apertures axis symmetry.

Enter in the sleeve pipe of water by the shower nozzle top, accelerate vertical drop to disc through the head natural gravity. Advantage of the present utility model:

1, the water spray angle is big;

2, water droplet is tiny, no umbrella;

3, water distribution is even, no hollow phenomenon;

4, pressure of supply water is low;

5, be difficult for stopping up;

6, sturdy and durable;

7, according to the replaceable sleeve pipe of discharge;

8, need not keep in repair.
